The process of valve seat generates noise pollution, this is environmentally friendly urgent problem instantly.In addition there are also the times of feed and lock gas to control
Coordination problem processed need to be handled strictly.Star-shaped feeding machine is charged using star-like impeller volume slot, will be above impeller when impeller rotates
Material be transferred to lower section.Due to impeller support shaft center be located at inlet and outlet channel centerline on, feed inlet into material to leaf
It is symmetrical for wheel shaft, therefore the torque that its material generates is balance, and the material above impeller is transferred to impeller
Lower section just needs additional driving power, consumes the energy；In addition, gap is larger between impeller and valve body, the problem of bringing is exactly to dissipate
Bulky grain in dress material be easy to cause valve bite, causes power of motor overload adjustment.The present invention is aiming above several
What the problem of aspect, was studied.
Summary of the invention
The purpose of this utility model is to provide a kind of squelch types for not needing configuration driven power and complex control to lock gas
Feed valve.
Design philosophy of the invention is that driving force is generated under the action of material gravity using the bias of impeller, saves driving
The energy, while using the single direction rotation of impeller, material blanking and lock gas coordination problem gram are answered, while also solving valve plate and valve
The noise that the shock of seat generates, has reached the requirement of safety in production.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of squelch type lock gas feed valve, including valve body, impeller, damping wheel, damping block, damper, axle envelope gland, axis
Envelope, valve end cap, impeller bearing, impeller shaft, blade, hopper, baffle and mounting rack, two of the impeller shaft in the feed valve
End is external to be equipped with impeller bearing, and impeller is through impeller bearing on valve end cap, and valve end cap bolt fastening is on valve body, valve end
Lid is equipped with axle envelope and axle envelope gland by impeller position, and end cap is equipped with mounting rack far from impeller end face, is respectively provided with resistance on mounting rack
Buddhist nun's block and damper, damping wheel are mounted on the outer end of impeller shaft, and valve body is mounted in the outlet of hopper by flange, hopper with
Valve feed inlet connects.
Each blade two sides on the impeller of the feed valve are welded with baffle, and the baffle and impeller at blade and both ends turn
Axis forms a whole, and three components constitute the material trough that can accommodate material on impeller.
Compared with prior art, the good effect of the utility model are as follows:
1, the impeller of the feed valve and valve passage bias, and impeller diameter is big, and side of valve body can facilitate setting maintenance door, fortune
Row easy maintenance；
2, the feed valve is cooperated using the self weight of material itself accumulation and impeller shaft installation site and the structure of impeller, real
Show the cooperative movement of lock gas and feed, it is simple and reliable；
3, the feed valve drives by material gravity, is fed in the same direction, realizes unpowered operation and automatic control, solves
Problem of noise pollution；
4, the feed valve is not hit, and would not generate vibration, and equipment is easy for installation, and the service life is longer；
5, the feed valve control design case passes through damper, damping block and damping wheel on the outside of the valve on damped control system
Wheel speed is adjusted, and it is convenient and reliable to adjust wheel speed.

Specific embodiment
Clear, complete description further is carried out to the technical solution of the utility model with reference to the accompanying drawing.
Referring to attached drawing 1-2, the impeller 2 in feed valve is mounted in by the impeller bearing 9 outside 10 both ends of impeller shaft
On valve end cap 8, axle envelope 7 and the use of axle envelope gland 6 that valve end cap 8 is filled in valve body 1, valve end cap 8 by 2 position of impeller with bolt fastening
In the sealing of valve body 1.Blade 11 and two end-stopping plates 15 on impeller 2 form a whole with impeller shaft 10, and three components exist
Multiple material troughs that can accommodate certain material are constituted on impeller 2.Material enters feed by hopper 13 and valve feed inlet 14
In valve, due to the hanging down relative to 12 material channel of valve feed inlet 14 and valve discharge port of impeller shaft 10 installed on impeller 2
There is certain eccentricity at straight center, therefore the gravity that the material that is loaded of impeller 2 generates will generate centainly impeller shaft 10
Torque push impeller 2 to generate rotation under the action of material gravity, realize from the upper valve feed inlet 14 of impeller 2 into
Material discharges from the valve discharge port 12 of lower part, so that the material in 1 top hopper 13 of valve body is ceaselessly passed through valve feed inlet
14 and valve discharge port 12 be transferred to next procedure.In order to which the speed to handling material controls, it is allowed to meet lower to production
